Description

Technical Field

[0001] The present invention belongs to the field of fabric detection, and specifically discloses an infrared fabric detection device. Background Art

[0002] Fabric infrared spectrum detection is a method for qualitatively and quantitatively analyzing fabrics through an infrared spectrometer. The infrared spectrometer obtains the infrared spectrum diagram of a substance by measuring the absorption, reflection, or transmission characteristics of the substance to infrared light. Different substances have unique absorption peaks on the infrared spectrum diagram, thus enabling qualitative and quantitative analysis of substances.

[0003] In the existing infrared fabric detection devices, the fabric clamping operation steps of some testers are relatively complex, requiring operators to have certain skills and experience. This not only increases the operation difficulty and time cost, but also during the operation process, due to the cumbersome steps, it is easier to make operation mistakes. Moreover, during the fabric preparation process, there may be differences in the processing technology and structural characteristics between the front and back sides of the fabric. Some require double-sided detection of the fabric, so the staff needs to remove and reinstall the fabric and then detect the back side of the fabric again, and the operation is rather cumbersome.

On both sides inside the square frame, there is a clamping mechanism for positioning the fabric. The clamping mechanism includes semi-circular grooves opened on both sides inside the square frame. Inside the semi-circular grooves, there are smooth rods rotatably installed. On the surface of the smooth rods, there are semi-cylinders. On the surface of the semi-cylinders, there are multiple convex points. At the four end corners of the square frame, there are activity grooves respectively. Inside the activity grooves, there are second springs. The ends of the second springs are connected with L-shaped sliders. On the side of the activity grooves, there are arc-shaped grooves. Inside the arc-shaped grooves, there are third gears rotatably installed. The ends of the smooth rods are fixedly connected to the third gears. On the surface of the L-shaped sliders, there are third racks, and the third racks are meshed with the third gears.

[0006] In the above technical solution, preferably, the driving mechanism includes a first gear rotatably installed in the middle of the frame box. Inside the frame box and in front of the first gear, there is a moving block slidably installed. Inside the frame box and behind the first gear, there are two first sliders symmetrically slidably installed. On the surface of the moving block close to the first gear, there is a first rack. On the surface of the first sliders close to the first gear, there are second racks. Both the first rack and the second rack are meshed with the first gear.

[0007] In the above technical solution, preferably, between the two first sliders, there are two support frames symmetrically installed. Between the two support frames, there is a second gear rotatably installed. On the surface of one of the support frames, there is a stepping motor. The output end of the stepping motor is connected to the second gear, and the second gear is meshed with the first gear.

[0008] In the above technical solution, preferably, a T-shaped slider is provided on the surface of the telescopic frame, a T-shaped sliding groove is opened at the bottom end inside the frame box, the T-shaped slider is slidably installed in the T-shaped sliding groove, and two second connection frames are symmetrically installed at one end of the telescopic frame inside the frame box.

DETAILED DESCRIPTION OF THE INVENTION

[0028] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0030] As Figures 1 - 10 shown, an infrared fabric detection device includes a detection mechanism 1. In the middle of the top of the detection mechanism 1, a frame box 2 is provided. At the bottom of the front of the frame box 2, an opening 3 is formed. Inside the opening 3, a telescopic frame 4 is movably arranged. Inside the frame box 2, a driving mechanism is provided. The driving mechanism can control the telescopic movement of the telescopic frame 4 at the opening 3. On the surface of one end of the telescopic frame 4 outside the frame box 2, a rectangular groove 20 is formed. Inside the rectangular groove 20, a square frame 22 is rotatably installed. At the middle of both sides of the square frame 22, a rotating shaft is provided. The rotating shaft is rotatably installed on the inner wall of the rectangular groove 20, so that the whole square frame 22 can rotate freely. On both sides inside the square frame 22, a clamping mechanism is installed. The clamping mechanism is used for positioning the fabric. By setting the driving mechanism, the telescopic movement of the telescopic frame 4 at the opening 3 can be operated, ensuring the consistency of the fabric detection position, reducing human error. At the same time, by setting the clamping mechanism, the end of the fabric can be clamped to realize the positioning of the fabric. By rotatably installing the square frame 22 inside the rectangular groove 20, the other side of the fabric can be detected, effectively improving the working efficiency without reinstalling the fabric and saving time.

[0031] The driving mechanism includes a first gear 6. The first gear 6 is rotatably installed in the middle of the frame box 2. Inside the frame box 2 and in front of the first gear 6, a moving block 5 is slidably installed. Inside the frame box 2 and behind the first gear 6, two first sliders 7 are symmetrically slidably installed. On the surface of the moving block 5 close to the first gear 6, a first rack 8 is provided. On the surface of the first slider 7 close to the first gear 6, a second rack 9 is provided. Both the first rack 8 and the second rack 9 are engaged with the first gear 6. Through the engagement of the first gear 6 with the first rack 8 and the second rack 9, the rotation of the first gear 6 can be converted into the linear motion of the moving block 5, and then drive the two first sliders 7 to perform linear motion, realizing the displacement of the moving block 5 and the first sliders 7. The first gear 6 is the core component of the drive. By only controlling the rotation direction of the first gear 6, the movement directions of the moving block 5 and the first sliders 7 can be accurately controlled, and then the telescopic degree of the telescopic frame 4 can be controlled.

[0032] Two support frames 12 are symmetrically installed between two first sliders 7. A second gear 11 is rotatably installed between the two support frames 12. The two support frames 12 position the second gear 11 to ensure the stability of the second gear 11 during use. A stepper motor 10 is installed on the surface of one of the support frames 12. The output end of the stepper motor 10 is connected to the second gear 11. The second gear 11 meshes with the first gear 6, further improving the drive mechanism. The stepper motor 10 directly drives the first gear 6 through the second gear 11.

[0033] T-shaped sliders are arranged on the surface of the telescopic frame 4. T-shaped chutes are opened at the bottom end inside the frame box 2. The T-shaped sliders are slidably installed in the T-shaped chutes. The cooperation between the T-shaped sliders on the telescopic frame 4 and the T-shaped chutes at the bottom end inside the frame box 2 can provide precise guidance for the telescopic movement of the telescopic frame 4, ensuring that the telescopic frame 4 expands and contracts along a predetermined linear trajectory, thereby improving the accuracy of fabric positioning and ensuring the precision of the detection position. At one end of the telescopic frame 4 inside the frame box 2, two second connection frames 19 are symmetrically installed. An extension block 13 is fixedly installed at the bottom of the first slider 7. A frame groove 14 is opened on the surface of the extension block 13. A guide post 16 is movably installed inside the frame groove 14. The surface of the guide post 16 movably penetrates through the extension block 13. A fixed disk is arranged at the top of the extension block 13. A first spring 15 is installed on the surface of the guide post 16 between the fixed disk and the frame groove 14. A first connection frame 17 is movably arranged below the extension block 13. The bottom of the guide post 16 is fixedly connected to the first connection frame 17. A connecting rod 18 is connected between the first connection frame 17 and the second connection frame 19 through a rotating shaft. The elastic force of the first spring 15 can make the top of the first connection frame 17 always close to the bottom of the extension block 13. When the first slider 7 slides upward towards the frame box 2, under the action of the connecting rod 18, the telescopic frame 4 will be pulled by a tensile force into the frame box 2. When the telescopic frame 4 completely moves into the frame box 2, the end face of the second connection frame 19 is close to the inner wall of the frame box 2. At this time, there is still a certain distance between the moving block 5 and the telescopic frame 4. Then the first slider 7 continues to move upward. The inner wall of the frame groove 14 exerts a squeezing force on the first spring 15, causing the first spring 15 to contract. The position of the telescopic frame 4 will not change, while the moving block 5 will continue to move downward. Finally, the pressing piece at the bottom of the moving block 5 will press the fabric tightly. This phased and logical movement mode precisely meets the operation requirements of positioning the fabric first and then pressing the fabric tightly during the fabric detection process, and the operation process is smooth and efficient.

[0034] A bottom groove 33 is provided at the bottom of the rectangular groove 20. A stopper 34 is slidably installed inside the bottom groove 33. A docking groove 23 is provided on the middle surface of the square frame 22. The docking groove 23 corresponds to the stopper 34. When the square frame 22 rotates inside the rectangular groove 20, the end face of the docking groove 23 will squeeze the surface of the stopper 34. The stopper 34 plays a limiting role to prevent the square frame 22 from rotating excessively in the rectangular groove 20, ensuring the accuracy of fabric detection. The cooperation between the stopper 34 and the docking groove 23 can ensure that the rotation of the square frame 22 is carried out within a safe and effective range.

[0035] The clamping mechanism includes semi-circular grooves 24, which are provided on both sides inside the square frame 22. A smooth rod 25 is rotatably installed inside the semi-circular grooves 24. A semi-cylindrical body 26 is provided on the surface of the smooth rod 25. Multiple convex points are provided on the surface of the semi-cylindrical body 26. The surface of the semi-cylindrical body 26 is movably arranged in the semi-circular grooves 24. The end of the fabric is installed in the semi-circular grooves 24. By squeezing the fabric with the semi-cylindrical body 26, the positioning of the fabric is realized. The end of the fabric can be directly placed into the semi-circular grooves 24, and then the positioning is realized by the extrusion of the semi-cylindrical body 26. There is no need for cumbersome fixing devices and complex operation steps. The operator can quickly complete the clamping of the fabric, improving the efficiency of the detection work. At the same time, the multiple convex points provided on the surface of the semi-cylindrical body 26 greatly increase the friction force with the fabric.

[0036] Moving grooves 27 are provided at the four end corners of the square frame 22. A second spring 30 is provided inside the moving grooves 27. The end of the second spring 30 is connected to an L-shaped slider 28, and the end of the L-shaped slider 28 protrudes into the docking groove 23. An arc-shaped groove 31 is provided on the side of the moving groove 27. A third gear 32 is rotatably installed inside the arc-shaped groove 31. The end of the smooth rod 25 is fixedly connected to the third gear 32. A third rack 29 is provided on the surface of the L-shaped slider 28. The third rack 29 meshes with the third gear 32. The presence of the second spring 30 provides a buffering effect for the movement of the L-shaped slider 28. During the detection process, even if there are some slight vibrations or external impacts, the second spring 30 can absorb part of the energy, avoiding hard collisions between the square frame 22 and the telescopic frame 4, protecting the equipment structure from damage, and at the same time reducing the possible displacement of the fabric caused by vibrations. And the elastic force of the second spring 30 can ensure that the L-shaped slider 28 always maintains a good meshing state with the third gear 32 during normal detection, ensuring the reliability of the transmission. When the staff installs the fabric, the L-shaped slider 28 can be pushed deep into the moving groove 27, so that the third gear 32 rotates, and the smooth rod 25 rotates synchronously. At this time, the semi-cylindrical body 26 will move out of the semi-circular groove 24, leaving a certain gap between the smooth rod 25 and the semi-circular groove 24. The end of the fabric can pass through the gap, and finally the thrust on the L-shaped slider 28 is released. The L-shaped slider 28 can automatically reset under the action of the second spring 30, realizing the clamping operation of the end of the fabric.

[0037] Two limit blocks 21 are symmetrically installed at one end of the telescopic frame 4 outside the opening 3, and the limit blocks 21 are installed at the end of the telescopic frame 4. When the telescopic frame 4 is completely retracted into the interior of the frame box 2, the limit blocks 21 can be close to the outer surface of the frame box 2, further ensuring the positioning of the position of the telescopic frame 4.

[0038] The stop block 34 is located between the two L-shaped sliders 28, and there is a certain distance between the stop block 34 and the L-shaped slider 28. There is a gap of 1 centimeter between the stop block 34 and the L-shaped slider 28 to prevent the stop block 34 from accidentally touching the L-shaped slider 28.

[0039] Working principle: First, start the stepper motor 10. The first gear 6 is directly driven by the second gear 11 to rotate forward. At this time, the whole moving block 5 moves upward above the frame box 2, and the whole first slider 7 moves downward below the frame box 2. Under the action of the first connecting frame 17, the second connecting frame 19 and the connecting rod 18, the telescopic frame 4 can be pushed from the opening 3 to the outside of the frame box 2. Then the staff pushes the L-shaped slider 28 deep into the movable groove 27, so that the third gear 32 rotates, and the optical rod 25 rotates synchronously. At this time, the semi-cylinder 26 will move out of the semi-circular groove 24. There is a certain gap between the optical rod 25 and the semi-circular groove 24. The end of the fabric can pass through the gap. Finally, release the thrust on the L-shaped slider 28. The L-shaped slider 28 can automatically reset under the action of the second spring 30 to realize the clamping operation of the end of the fabric. Then the staff rotates the square frame 22 to keep the square frame 22 horizontal. Next, start the stepper motor 10. The first gear 6 is directly driven by the second gear 11 to rotate reversely. At this time, the whole moving block 5 moves downward below the frame box 2, and the whole first slider 7 moves upward above the frame box 2. Under the action of the first connecting frame 17, the second connecting frame 19 and the connecting rod 18, the telescopic frame 4 can be pulled from the opening 3 to the inside of the frame box 2. When the telescopic frame 4 is completely moved into the frame box 2, the limit block 21 is close to the outer surface of the frame box 2, and the end face of the second connecting frame 19 is close to the inner wall of the frame box 2. At this time, there is still a certain distance between the moving block 5 and the telescopic frame 4. Then the first slider 7 continues to move upward. The inner wall of the frame groove 14 has a squeezing force on the first spring 15, causing the first spring 15 to contract. The position of the telescopic frame 4 will not change, while the moving block 5 will continue to move downward. Finally, the pressing piece at the bottom of the moving block 5 will press the fabric tightly to realize the detection of the fabric. Since the materials of the fabrics are different, when facing fabrics with double-sided materials, the other side of the fabric needs to be detected. At this time, the telescopic frame 4 needs to be moved to the outside of the frame box 2 again. The staff directly flips the square frame 22, and then operates the telescopic frame 4 to move into the frame box 2, that is, the double-sided detection of the fabric can be realized.
